What effect would constriction of the blood vessels have in the body

higher blood pressure

Explanation:

when the vessels constrict they get smaller therefore in order for the blood to be pumped through the body the heart would have to work harder resulting in a higher blood pressure

increased blood pressure resulting in risk of heart attack

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

the principle of segregation describes how pairs of gene variants are separated into reproductive cells. from his data, mendel formulated the principle of segregation. we now know that the segregation of genes occurs during meiosis in eukaryotes, which is a process that produces reproductive cells called gametes.
